Paguritta
Paguritta is a genus of anomuran decapod crustaceans, commonly known as squat lobsters. They are distinguished by their distinctive flattened bodies and the characteristic habit of carrying sponges or other organisms on their backs for camouflage and protection. This genus belongs to the family Paguridae, which also includes true hermit crabs.
Characteristics
Squat lobsters of the genus Paguritta exhibit several key features that differentiate them from other anomurans. They possess a broad, flattened carapace that is often covered with a dense layer of setae (hairs). Their abdomen is reduced and lacks the characteristic spiral shape found in true hermit crabs. Additionally, Paguritta species are known for their peculiar habit of carrying sponges, bryozoans, or algae on their backs, effectively camouflaging themselves against predators.
Environments
Paguritta species are found in a variety of marine environments, primarily in the Indo-Pacific region. They are commonly encountered on coral reefs, rocky shores, and seagrass meadows, where they forage for food among the substrate. Their flattened bodies allow them to maneuver easily among crevices and under rocks, providing them with a degree of shelter from predators.
